What do the port states in the switchshow output of a Brocade Fibre Channel director or switch mean, and which of them point at the transceiver rather than the fabric?
We run a couple of IBM Power boxes next to a small SAN, and I am trying to write down a sane spares policy before the next hardware maintenance renewal. The part I cannot pin down is the transceiver itself: on some adapters it looks like a field-replaceable part in its own right, on others a…
I am putting together a switchless Fibre Channel setup at home: one box holds the storage and has to act as the FC target, the other two are plain initiaators. No FC switch in the middle, just direct cables between HBAs. Hardware: QLogic QLE2694 in the storage box, the one that should be the target…
We are adding capacity to a small FC fabric and bought compatible 16G short-wave SFP+ from an optics supplier instead of paying the switch vendor price. The switch refuses them. Brocade G610, Fabric OS 9.x generic-coded 16G SWL SFP+, correct wavelength and reach according to the label Brocade-coded…
A DS14-MK4 shelf came my way for almost nothing and I would like to hang it off an ordinary tower server as bulk storage at home. It is fully populated with its original carriers, it powers up, fans spin, front panel looks alive - but I cannot get a single disk to appear on the host. NetApp…
Running a small virtualization setup: two Proxmox 6 nodes and a target on FreeNAS 11.2. While the HBAs were connected to the target directly, everything ran for months without a single error. Put a used Brocade 200e between them to avoid crossing cables, and that's when it started. two Proxmox 6…
One host in a blade chassis went to ESXi 8.0 U3 and came back with no Fibre Channel at all. The datastores are gone, the adapters are not in the storage adapter list, and nothing logs in on the fabric side for those ports. The rest of the cluster is untouched and still sees the same LUNs. blade…
We are adding a G610 to an existing fabric and there is a box of non-Brocade 16G/32G FC SFP+ left over from another build. Before I plan any ports around them I put one into a spare port on the bench to see what the switch makes of it. Brocade G610, Gen 6 third-party 32G FC SFP+, no Brocade…
Moving a pair of hypervisors onto Fibre Channel storage, and one host refuses to present a single LUN while the very same hardware works when the card is handed to a VM. QLogic QLE2692, ISP2722-based 16/32Gb FC, both ports cabled Fujitsu Eternus DX100 S5 at the other end Proxmox VE 6.2 host…
We inherited a pair of Connectrix DS-7720B (Brocade G720) for a new fabric, and I haven't got anywhere near zoning yet, because not one of the double density ports will come up. Every single one of them says the same thing in switchshow: What is in the rack: Connectrix DS-7720B / Brocade G720…
The poster wanted to verify whether an HPE StorageWorks 81B 8 Gb Fibre Channel HBA (AP769-60001) fitted with an AJ716B SFP could be used in an HPE ProLiant DL380 Gen10 server (P02464-B21) and asked for a tool where part numbers can be entered to get a compatibility verdict. No error had occurred…
The poster owned a MikroTik RB962UiGS-5HacT2HnT (hAP ac) with a single SFP cage and had two spare 850 nm modules on hand: a Cisco-branded AFBR-57F5PZ-CS1 and an Intel-branded FTLX8571D3BCVIT1. The ISP delivered the service over a single fibre strand rather than a duplex pair, and the posster wanted…
